## Study notes

- J3 is a vertical linear axis with a 300 mm stroke (450 mm option) and a 2800 mm/s maximum speed, so it is not represented in the degree-based joints list.
- Repeatability is ±0.01 mm on J1-J3 and ±0.005° on J4.
- The robot footprint is 280 × 364 mm, and cables and pipes are routed internally.
- The controller series is R-30iB Plus; the compatible controller is R-30iB Compact Plus.
- Programming uses the web-based iRProgrammer interface from a tablet or desktop, or an optional teach pendant.
- Push force is 250 N; the J4 inertia rating is 0.3 kg·m².
